SharePoint Backups Won't Start

 

Hi All,

 

I ran across this problem at more than one site.  When you go into Central AdministrationàOperationsàBackup and Restore  and attempt to queue a SharePoint backup, it appears to simply sit there without ever starting.  The status message reads “Status: Preparing current backup/restore job. If the backup/restore job does not begin after five minutes, make sure that the SharePoint Timer Service is running.”  Normally the job starts within seconds, but now it never begins.  If you click “Timer Job Definitions” you see that there is an object named “Backup/Restore”, but if you go to Timer Job Status, you see that it is not running.

 

Clicking “Refresh” is about as effective as repeatedly pushing the elevator call button to make it hurry up.

 

No errors or messages appear in the event logs.  This is unusual because SharePoint is very prolific in its errors when something is wrong.  Even delving into the SharePoint logs at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\ bears little useful information. 

 

I’ve seen this both on MOSS and WSS servers.

 

Well, I did a little digging and I found someone else who is having the same problem.

It appears that the recent Daylight Savings Time patch (or the subsequent clock change) has screwed something up in the SharePoint timer.  What’s going on it that the job is starting very, very late.  Furthermore, once it starts, it apparently takes a longer time to finish.  A couple of people reported that when they modified the DST clock settings on the server hosting their WSS sites so that it would not “Automatically adjust clock for Daylight Savings Time”, the problem vanished. 

 

I haven’t been able to verify this, since I am currently at a site where the WSS implementation is sitting on a domain controller.  Rolling the clock back on a DC isn’t a smart move.

 

Have any of you seen this issue?

I have now verified the problem on the server I'm currently working on.  The backup job started exactly one hour late.  And it drags.  What used to take a few seconds to complete is taking much longer.  It's still in progress, in fact.  The archive is only 900MB but we're going on 20 minutes.  

One thing to note: neither of the servers I've seen this problem on have Sharepoint 2007 SP1 installed.

Just move the time on the SharePoint Server with one hour (ahead or backwards, depending on the time of the year) and voila!, the job kicks in. The bad part - the start time of the job can be later than the finish time... if the job takes less than an hour. Or a lot earlier -(1 hr + the time it takes to finish the job). I have not seen this to be a problem for restoring the backup at a later time. But it is always a good thing to update with SP1, which fixes the issue.

Thanks, I will try that.  Ironically, on the MOSS server, I was backing up the farm so I could apply SP1.

There is a hot fix for it. See support.microsoft.com/.../938663. For MOSS, you still need to apply the hotfix for WSS first.

I had the same problem and the hot fix solved the problem.

Good luck!

I installed Service Pack 1 and the backup issues went away.  

One side effect of the SP1 installation seemed to be in the area of security.  I got a ton of DCOM errors stating that my farm and search service accounts did not have local activation rights.  Granting them these specific permissions via the Component Services applet solved the problem.

The problem with my backups is that it never starts, I had a backup initiated for several days and it never did start.  When I refresh the status I don't get no results...

Have anyone experienced their backups not starting at all with out any errors being reported?
